What are the network security traps?

What are the network security traps? Internet fraud is now the most common means of fraud, because people's daily consumption or money is generally carried out through the Internet or online, so it also provides an opportunity for criminals. Let's take a look at the network security trap.

1 What are the network security traps? First, criminals pretend to be well-known companies, especially banks, through e-mail, in the name of system upgrade, to trick unsuspecting users into clicking on fake websites, and at the same time require users to enter their own account numbers, online banking login passwords, payment passwords and other sensitive information. If the masses are not careful, criminals may use fraudulent accounts and passwords to steal customers' funds.

Second, criminals use online chat to sell online game equipment, digital cards and other commodities at low prices as netizens, and trick users into logging in to the fake website address provided by criminal suspects, and enter bank account numbers, login passwords and payment passwords. If the masses are not careful, criminals will use fraudulent accounts and passwords to illegally occupy customer funds.

Third, criminals take advantage of some people's bad online habits, such as downloading and opening some unknown programs, games and emails. , and may implant Trojan virus into customers' computers through these programs and emails. Once people use this "poisoned" computer to log in to online banking, customers' accounts and passwords may be stolen by criminals. When people surf the Internet on public computers such as Internet cafes, computers in Internet cafes may be implanted with Trojan horses in advance, and sensitive information such as account numbers and passwords may also be stolen in this environment.

Fourth, criminals take advantage of the psychology that people are afraid of trouble and the password setting is too simple, and may guess people's passwords by testing their personal birthdays.

Special instructions:

First, log on to the right website. Please go directly to the website when visiting the bank website. Be careful to identify fake websites; Protect your account and password; Don't tell others your account number and password at any time and under any circumstances; Don't trust any behavior of asking for card number and password by email, SMS, telephone, etc.

The second is to ensure computer security, and regularly download and install the latest operating system and browser security programs or patches; Install a personal firewall; Install and update antivirus software in time.

What are the network security traps? 2. Take stock of the top ten threats to network security.

1. computer virus-a program or executable code that spreads through self-replication will affect the normal operation of the computer.

2. Worm virus-can spread through USB devices or email attachments, which will affect the sending and receiving of email.

3. Trojan horse-it won't copy itself, nor will it intentionally "infect" other files, but it will leave the computer unguarded and easily controlled by hackers.

Spyware-secretly installed on the computer without consent, constantly feeding back the operator information to the controller of the software.

5. Adware programs-usually in the form of pop-up windows, will not directly harm the computer, but may become the carrier of spyware.

6. Spam-It can be used to send different types of malware, and it may also have a bad influence on the mail server.

7. Phishing-fraudulent activities are carried out through fake emails and fake websites, and the deceived usually reveal important private information and materials.

8. Website Grafting-a more complicated form of phishing, which uses DNS system to establish fake websites to obtain information of the deceived.

9. Keylogger-It can record the user's operations on the keyboard, and hackers can search for specific information, such as account passwords.

10. Fake security software-pretending to be security software, giving false alarm, inducing users to uninstall real security software, so as to steal information such as online payment.

Second, the threat of network security will become the biggest threat in the digital age.

Chairman of the weekly conference, founder and chairman of 360 disclosed for the first time at the 9th Internet Security Conference: "360 * * * captured 46 national hackers abroad, and monitored more than 3,600 attacks, involving more than 20,000 targets. In the first half of this year alone, 360 captured 12 APT organizations that attacked China. "

According to Zhou, from last year to the first half of this year, network security incidents occurred frequently around the world, and various attacks such as supply chain attacks, blackmail attacks, industrial control equipment attacks, APT attacks and data theft emerged one after another. Cyber attacks have also become a hot topic of confrontation among great powers. "In the future, cyber forces, APT organizations and organized cybercrime under the national background will become the biggest threat to cyber security. The targets and methods of cyber attacks will break through the convention and threats will continue to escalate to the high end. "

Zhou said that digitalization has three characteristics: everything is programmable, everything must be interconnected, and big data drives business. The essence is that software defines the world, and cities, cars and networks will all be defined by software. This also means that digitalization makes the whole network security environment more fragile, security risks more ubiquitous, and private information more vulnerable to attacks.

Third, some countermeasures to realize network security construction.

Although computer network security is constantly threatened by many factors, the security of network information can also be effectively protected if appropriate protection measures are taken.

3. 1 Strengthen the safety awareness of operators and users.

Computer systems usually use passwords or passwords to control access to system resources, which is one of the simplest and most economical methods. Network administrators and terminal operators choose different passwords according to their respective responsibilities and rights, and operate application data legally to prevent users from accessing data and using network resources beyond their authority.

3.2 Strengthen the system security protection technology

For example, network firewall technology and network honeypot technology.

Network firewall has the functions of filtering unsafe services, illegal user access, providing internet security monitoring and early warning. It is at the bottom of network security, and is responsible for the transportation and transmission between network security. With the overall development of network security technology and the continuous evolution of network applications, modern firewall technology not only completes the filtering task of traditional firewalls, but also provides corresponding network security services for various network applications.

Network honeypot technology. Honeypot is a computer system running on the internet, which is specially used to attract and induce those who try to illegally invade other people's computer systems. Honeypot system is a fraud system with loopholes, which provides an easy target for attackers by simulating one or more vulnerable hosts.

Honeypot doesn't provide real valuable information to the outside world. It's just a trap. The purpose is to let attackers waste time on honeypots and delay their attacks on real targets. After the attacker invades the honeypot, the user can know how he conquered it, so as to keep up with the latest attacks and loopholes in network information transmission at any time and intercept it.

What are the network security traps? 1. What are the common means of network security network fraud?

1, using QQ, MSN and other online chat tools to implement fraud. The suspect steals the number and password by hacking and compulsory video recording software, and records the video image of the other party. Then he logged into the stolen QQ number to chat with relatives and friends, and played the recorded video to relatives and friends to defraud trust, and then borrowed money for fraud in the name of urgent need of money.

2, the use of online game equipment and game currency transactions to implement fraud. Criminals use an online game to buy and sell game coins and equipment. After defrauding the player's trust, let the player remit money through the offline bank, or cheat by stealing the number after the transaction.

3. Use online banking to commit fraud. Criminals make "phishing" pages similar to some banks in official websites, steal online banking information, and take cash from accounts.

4. Online shopping fraud. There are mainly the following categories: criminals provide false links or web pages for the victim, and the transaction shows unsuccessful, and they make multiple remittance frauds; Refuse to use the third-party secure payment tool on the website, and cheat in private transactions; Collect deposits first and then fabricate reasons to induce victims to add deposit fraud; Cheating by passing off fake and cheap cottage products as brand-name goods.

5. Online winning fraud. Criminals use communication software to randomly release winning tips to Internet QQ users, MSN users, email users, online game users and Taobao users. When the victim consults and verifies according to the designated "telephone" or "webpage", criminals ask the victim to remit money for various reasons such as winning the prize and paying taxes.

6. Pretending to be a staff member of the Public Security Law to commit telecom fraud. Criminals pretend to be public security personnel, falsely claiming that the victim's identity information was fraudulently used or leaked by others under the pretext of telephone arrears, court summons investigation and parcel hiding, and bank accounts were suspected of money laundering, fraud and other criminal activities. In order to ensure that the victim is not damaged, the bank deposit is transferred to the so-called "safe account" provided by the other party.

Second, the composition characteristics of cyber crime

All kinds of complex relationships in real society can be reflected in the network. As far as the general object of cyber crime infringement is concerned, it is naturally all social relations protected by criminal law and infringed by cyber crime.

However, it should be noted that the Internet is a virtual space formed by connecting computers and does not actually exist. As far as the Internet is concerned, this connection is maintained by two pillars, one is technical TCP/IP.

The other is the principle that users enjoy resources. It is these two pillars that make national boundaries and continental boundaries disappear completely and make virtual space form.

The cyber crime here infringes on a complex object, and the similar object infringed by cyber crime should be the public order in which information exchange can be carried out normally on the network.

The direct object of infringement should be the ownership of public and private property. It should be pointed out that using the internet to cheat does not belong to this crime.

Third, how to report online fraud cases?

1, local report. Because online fraud is suspected of a crime, the first step must be to bring all the evidence (such as chat records, payment vouchers, product web pages, etc.). , print and provide written documents) and report to the network police department of the network supervision public security organ (preferably the district public security department, the police station basically has no corresponding police types), and the next investigation and handling can be carried out only after the case is filed.

2. Disclosure process. Professional websites such as online transaction protection center, as industry organizations or third-party institutions, are not state law enforcement agencies and have no law enforcement power. They can only play the role of information disclosure, that is, by publishing your complaint information, help more netizens avoid being fooled. Complaint information can educate consumers and play the role of early warning and prevention, so it is valuable for netizens to publish complaint information on such websites.

3. Find the victims in the same case. Because online fraud is mostly small transactions and involves many law enforcement departments (public security, industry and commerce, telecommunications management, etc.). ) and commercial organizations (banks, third-party payment companies, telecommunications, Internet service providers, etc. ), coupled with cross-regional or even cross-border, the cost of solving crimes is high and it is difficult to solve crimes. It is suggested that netizens should take the form of collective reporting by looking for people in the same situation, which can attract the attention of the police and reduce the cost of solving crimes.
